ET4035 - 50Amp Circuit Breaker

ET4035 - 50 Amp Circuit Breaker

When you're working with an existing electrical setup, the last thing you want is a breaker that almost fits. The ET4035 molded case circuit breaker is built to match the specs you need—50 amps, 3 poles, and designed for use in F-frame systems—so you can get things back up and running without unnecessary adjustments. It handles standard protection duties, such as overloads and short circuits, while maintaining the same footprint and connection style as your equipment was designed for. Rated at 14k A.I.C. at 480VAC, this breaker is well-suited for typical commercial and light industrial environments. It's designed to operate at 40°C, which covers most everyday applications. Whether you're replacing a failed unit or keeping your system consistent with existing components, the ET4035 provides a straightforward, reliable solution that does exactly what it's supposed to.
